Making it all 3D!

Just replace your 2D webcam with a 3D camera (on a tripod). They are pretty cheap now (this one's around £30 from Amazon). While the process of taking 3D images is a pretty straight forward one, making the movie is not so easy!The above camera takes 3D pics using the side-by-side method.Easy Way: Upload you movie to youtube as 3D video. Done. View with 3D glasses.Hard Way: Use a decent video editing package to overlay and colourise the images. Done. Eventually. View with 3D glasses.
